FACILITY FOR REAGENT BATCHING AT OIL EXTRACTION OUT OF WELL

摘要

FIELD: mining. ^ SUBSTANCE: facility includes container for reagent with piston and rod, pipeline communicating rod end with annular space and/or flow line of well, pipeline communicating blind side with flow line, slide valves and throttles on pipelines, sleeve for filling reagent into container in rod end and gauge for reagent consumption. As a consumption gauge a calibrated rod with a scale is used. The rod is equipped with a spring fixed at the piston and container; the said spring stretches with piston movement and forms a remaining volume of the rod end with an operating stretching range of the spring within limits of 10 to 90% from maximum. The blind side is filled with hydrocarbon gas and light crude. The reagent container is installed vertically. ^ EFFECT: upgraded reliability of reagent batching. ^ 1 dwg
